The cardiovascular system consists of the heart‚ blood vessels‚ and blood. This system has three main functions: Transport of nutrients‚ oxygen‚ and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide‚ nitrogenous wastes). Atria: Ventricles: In a four-chambered heart‚ such as that in humans‚ there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs‚ and the left ventricle pumps

more than 200‚000 deaths annually. Sepsis is a complex condition that results from an infectious process that represents the body’s response to infection and involves systemic inflammatory and cellular events that result in altered circulation and coagulation‚ endothelial dysfunction and impaired tissue perfusion (Kleinpell‚ 2005). Associated mortality rates with sepsis in the United States have remained largely unchanged for several decades. Through an international collaboration known as the Surviving

The Filoviridae family of viruses is where the Ebola virus belongs. The virus is distinguished by long filamentous structure which can present as straight‚ branched‚ and circular or a folded strand with a uniform diameter of approximately 80 nm but can be many different lengths. Liver cells‚ neutrophils‚ endothelial cells and macrophages are specifically targeted by the virus. Large quantities of cytokines are created by infected cells which solicits a large response from the immune system and interrupts

What is Dengue fever? Dengue fever (pronounced Den-gay) is a viral infection caused by the female mosquito (Aedes aegypti and Aedes albopictus). Dengue fever occurs in tropical and sub-tropical regions and usually increases in the hot and humid months. Dengue fever is not a new disease. It was discovered several hundred years ago. In recent years‚ dengue fever has become a major international public health concern. Dengue fever nicknamed "breakbone fever" because dengue patients usually express

by Flemish nuns. It remained largely obscure until 1989 when several widely publicized outbreaks occurred among monkeys in the United States. The virus interferes with the endothelial cells lining the interior surface of blood vessels and with coagulation. As the blood vessel walls become damaged and destroyed‚ the platelets are unable to coagulate‚ patients succumb to hypovolemic shock. Ebola is transmitted through bodily fluids‚ while conjunctiva exposure may also lead to transmission. There are

The high amount of platelets in this tissue is beneficial to the body because it has coagulation factors that help stop bleeding (Laparoscopic‚ 2013). Not only does it contain platelets‚ but the red pulp also contains

STERILIZATION AND DISINFECTION Definitions Bacteriostatic Agent: An agent that inhibits the growth of bacteria‚ but does not necessarily kill them. Bactericide: An agent that kills bacteria. Most do not kill Endospores. Sporicide: An agent that kills spores. Definition STERILIZATION The process of freeing an article from microorganisms including their spores. By definition‚ it effects a reduction in the number of microorganisms (more than 99.9999% are killed). Methods

Dengue fever is a disease caused by one of a number of viruses that are carried by mosquitoes. These mosquitoes then transmit the virus to humans. The virus that causes dengue fever is called an arbovirus‚ which stands for arthropod-borne virus. Mosquitoes are a type of arthropod. In a number of regions‚ mosquitoes carry this virus and are responsible for passing it along to humans. These regions include the Middle East‚ the far East‚ Africa‚ and the Caribbean Islands. In these locations‚ the
